unknown encoding name "chunked\r\n\r\n25" for http-parser-java

Hi. I've just installed jekyll on my machine and when doing gem install jekyll bundler everything gets installed correctly except for the following message from your gem:

...
Parsing documentation for i18n-1.14.3
Installing ri documentation for i18n-1.14.3
Parsing documentation for http_parser.rb-0.8.0
unknown encoding name "chunked\r\n\r\n25" for ext/ruby_http_parser/vendor/http-parser-java/tools/parse_tests.rb, skipping
Installing ri documentation for http_parser.rb-0.8.0
Parsing documentation for eventmachine-1.2.7

It would be nice to fix this message so the installation is done completely clean.
Thx!
